Send it out. There are a few people in Europe who will help you. I sent razors to Bruno and was very happy.
I would offer to hone for you but I have limited access to my stones at the moment as I am away from home.
Other people to try might be Lx emergency, and I think poona also is offering honing now.
Don't give up, once you have a sharp razor it all gets much easier!
I think your coticule should be fine for honing. It is much larger than my one and I manage ok. Get your razor sharpened and consider buying a cheap ebay razor to practice honing on. It is a worthwhile investment. The wapienica razors are great to learn to hone on.
